Twin Zygosity Tests

Are my Twins IDENTICAL?

Identical twins occur when a single fertilized egg splits sometime within the first few days after fertilisation. This accounts for around 30% of twins. When the young embryo splits, each half takes the exact same DNA, so identical twins have exactly the same genetic makeup.

Are my twins SEMI-IDENTICAL?

Semi-identical or fraternal twins are created by two separate eggs and two separate sperm that are fertilised during the mother's same menstrual cycle. These types of twins share half their genetic information and are no more or less similar than normal siblings.

For $159 we will DNA profile both twins to see if they have the exact same DNA profile (being identical twins), or if they each have their own DNA profile (as with non-identical twins and siblings). To take this test at our unique price, you can either call us on 1800-000-362 or click to order the DNA collection kit (mouth swab).

Semi-identical twins is a new discovery to science, and we have the ability to also test for these types of twins. To test for Semi-identical twins we need to analyse the DNA from both twins and both the parents
